As shown in FIG. 1 to FIG. 42 , one embodiment of the presentapplication discloses water divider structure. The water dividerstructure includes a pressure source 1300, a water divider 1400, and afirst unidirectional valve 1430. The pressure source 1300 is used toconnect a water supply tank 1200, and the water divider 1400 includes afirst distribution channel 1410 and a second distribution channel 1420,both of which are connected to the pressure source 1300. The firstunidirectional valve 1430 is connected between the pressure source 1300and the water divider 1400. The first unidirectional valve 1430 is ableto connect the pressure source 1300 and the water divider 1400 under thepressure formed when the pressure source 1300 is activated.

The pressure source 1300 can be applied by a water pump. When thepressure source 1300 is turned on, the water of the water supply tank1200 can be supplied to the water divider 1400, thereby generating alarger water pressure. Only then can a sufficient water pressure valuebe generated to open (turn on) the first unidirectional valve 1430. Whenthe pressure source 1300 is turned off, the water in the water supplytank 1200 cannot generate enough water pressure, and then the firstunidirectional valve 1430 cannot be flushed, so that when a main body isshut down or stops working, the water in the water supply tank 1200cannot pass through the first unidirectional valve 1430.

When there is residual water in the channel between the firstunidirectional valve 1430 and the water divider 1400, the firstunidirectional valve 1430 prevents the water in the water supply tank1200 from being transported downstream. At this time, one end of thewater channel downstream of the first unidirectional valve 1430 isclosed, and one end of the water divider 1400 is connected to the air.Under the action of atmospheric pressure, the sealing effect of thefirst unidirectional valve 1430 prevents the water in the channelbetween the first unidirectional valve 1430 and the water divider 1400from flowing out of the main body, solving the problem of water leakageand ensuring the cleanliness of the ground.

In one embodiment, the first distribution channel 1410 and/or the seconddistribution channel 1420 is provided with a second unidirectional valve1440. The second unidirectional valve 1440 can open (turn on) the firstdistribution channel 1410 and/or the second distribution channel 1420 ata pressure formed when the pressure source 1300 is activated. The secondunidirectional valve 1440 can close one end of the first distributionchannel 1410 or the second distribution channel 1420 and open the otherend of the first distribution channel 1410 or the second distributionchannel 1420 when the first unidirectional valve 1430 is closed (turnedoff). Under the action of atmospheric pressure, no matter how the heightand horizontal inclination of the first distribution channel 1410 or thesecond distribution channel 1420 change, that is, no matter how the mainbody shakes, the water remaining in the main body does not flow outalong the first distribution channel 1410 or the second distributionchannel 1420. It avoids the problem of water leakage after the main bodyis stopped or the pressure source 1300 stops working.

The design principle is that when both ends of a water pipe with waterare open, as long as the heights of the two ends of the water pipe aredifferent, the water in the water pipe will leak out, but if one end ofthe water pipe is blocked, no matter how the water pipe is placed, nomatter whether the water pipe is vertical or horizontal, even if thereis a height difference between the two ends of the water pipe, the waterin the water pipe still does not leak out of the water pipe if the twoendsare not at the same height.

It should be noted that, the first unidirectional valve 1430 or thesecond unidirectional valve 1440 can be selected from a softunidirectional valve, a mechanical spring valve, an electronic valve,etc. For example, when a soft unidirectional valve is used, the firstunidirectional valve 1430 or the second unidirectional valve 1440 mayinclude a main pipe section 1431 and a flexible pipe section 1432. Theinner cavity of the flexible pipe section 1432 is in communication withthe inner cavity of the main pipe section 1431, and the inner pipe wallsof the opposite sides of the flexible pipe section 1432 are fitted andclosed with each other. The inner pipe walls on opposite sides of theflexible pipe section 1432 can be separated at the pressure levelsformed when the pressure source 1300 is activated. Therefore, only thehydraulic pressure formed when the pressure source 1300 is activated cancause the soft unidirectional valve to open. Alternatively, for example,when a mechanical spring valve is used, the liquid can flow out of themechanical spring valve only when the hydraulic pressure is greater thanthe elastic force of the spring in the mechanical spring valve. Or, forexample, when an electronic valve is used, the first unidirectionalvalve 1430 or the second unidirectional valve 1440 can be automaticallycontrolled to close when the main body is turned off or the water pumpis not working.

In one embodiment, a water tank structure, including a water supply tank1200, water outlet pipe 1370, and the water divider structure, isprovided. The water supply tank 1200 has a tank top section 1310 and atank bottom section 1320,and the tank bottom section 1320 of the watersupply tank 1200 is provided with a water outlet 1360 and an air inlet1341. The water supply tank 1200 has a water storage cavity, and thewater storage cavity of the water supply tank 1200 is divided into atleast two inner cavity sections 1330 from a direction of thetank topsection 1310 of the water supply tank 1200 to the tank bottom section1320 of the water supply tank 1200. The cross-sectional area of aplurality of the inner cavity sections 1330 is gradually reduced, andthe cross-sectional area is perpendicular to the direction from thetanktop section 1310 of the water supply tank 1200 to the tank bottomsection 1320 of the water supply tank 1200. One end of the water outletpipe 1370 is connected to the water outlet, and the pressure source 1300of the water divider is connected to the other end of the water outletpipe 1370.

The gradual reduction of the cross-sectional areas of the plurality ofinner cavity sections 1330 of the water supply tank 1200 canspecifically be expressed as the gradual reduction of the widths ofdifferent inner cavity sections 1330. That is, the width of theplurality of inner cavity sections 1330 of the water supply tank 1200gradually decreases in the direction from the tank top section 1310 tothe tank bottom section 1320. When the water supply tank 1200 isinstalled in the main body, comparing with adesign that keeps theoverall cross-sectional area of the water supply tank 1200 the same, thedesign of the different cross-sectional areas in the plurality of innercavity sections 1330 is advantageous because the water flow rate ininner cavity section 1330 with smaller cross-sectional area is faster sothat it can still ensure that the water outlet speed of the water supplytank 1200 remains relatively constant even after the water level drops.The above design will not cause the water flow in the water supply tank1200 to be significantly reduced due to the reduction of the watervolume so as to improve the water outlet efficiency of the water supplytank 1200 and reduce the impact on the water outlet speed. Thereby, thewater outlet speed of the water supply tank 1200 is made more uniformand stable, and the cleaning efficiency of the cleaning equipment isimproved.

In one embodiment, a water outlet structure is provided on the watersupply tank 1200. More precisely, the water outlet structure is providedat the tank bottom section 1320. The water outlet structure includes ablocking member 1350, a water outlet 1360, and an air inlet 1341.Thewater outlet 1360 and the air inlet 1341 both communicate with thewater storage cavity. The blocking member 1350 is used to elasticallyblock the water outlet 1360, thereby, when the water supply tank 1200 isseparated from the main body, the blocking member 1350 can block thewater outlet 1360 by using elastic force, so that the water inside thewater supply tank 1200 cannot flow out from the water outlet 1360. Whenthe water supply tank 1200 is assembled with the main body, acorresponding structure can be provided to overcome the elastic force ofthe blocking member 1350, so that the blocking member 1350 can releasethe blocking of the water outlet 1360. Then, the water in the watersupply tank 1200 can flow out through the water outlet 1360 and besupplied to the outside of the roller brush or the main body under thedriving action of the pressure source 1300.

In one embodiment, the water tank structure includes a tank cover 1340,the water outlet 1360 is opened on the tank bottom section 1320, and thetank cover 1340 is configured on the water outlet 1360. The tank cover1340 is provided with an external port 1343 that communicates with thewater outlet 1360, and the blocking member 1350 is configured on thetank cover 1340. The blocking member 1350 is used to elastically blockthe external port 1343, thereby blocking the water outlet 1360 further.The air inlet 1341 is opened on the tankcover 1340, and the main body isprovided with a top-opening portion. The water supply tank 1200 isinstalled on the main body, and the top-opening portion is in abutmentwith the blocking member 1350 for pushing up the blocking member 1350 toopen the water outlet 1360. At this time, as a structure for overcomingthe elastic force of the blocking member 1350, the top opening portioncan be mutually matched with the structure of the blocking member 1350,which can be structures such as pillars or bumps.

The tank cover 1340 can be assembled on the water outlet 1360 of thewater supply tank 1200 through a screwed structure and be configured asthe blocking member 1350 on the tank cover 1340. After screwing off thetank cover 1340, the water outlet 1360 of the water supply tank 1200 canalso be used as a water inlet for replenishing water into the waterstorage cavity of the water supply tank 1200, so as to facilitate thewater supply of the water supply tank 1200. Furthermore, there is noneed to open a separate water inlet on the water supply tank 1200.Alternatively, the blocking member 1350 elastically assembled on thetank cover 1340 can also be directly designed at the position of thewater outlet 1360 of the water supply tank 1200, so that the tank cover1340 is removed, and an independent water outlet 1360 is designed inaccordingly. Those skilled in the art can select a corresponding designstructure according to requirements, which is not limited here.

In one embodiment, a limiting stage 1351 is provided in an external port1343, and a limiting portion 1352 is provided on the blocking member1350. The blocking member 1350 is elastically assembled in the externalport 1343 through an elastic member. The limiting portion 1352 of theblocking member 1350 is in elastic contact with the limiting stage 1351through the elastic force exerted by the elastic member. The limitingportion 1352 and the limiting stage 1351 elastically contact each otherto block the external port 1343.

The mutually abutting surfaces of the limiting stage 1351 and thelimiting portion 1352 can be planes that cooperate with each other orcan be inclined surfaces that cooperate with each other. When thelimiting stage 1351 and the limiting portion 1352 are in contact witheach other, and the surface of the limiting stage 1351 and the surfaceof and the limiting portion 1352 are in contact with each other as well,the external port 1343 is well blocked, and then, in sequence, the wateroutlet 1360 can be blocked by blocking the external port 1343. Itprevents the water in the water supply tank 1200 from flowing outthrough the water outlet 1360. Only when the elastic force exerted bythe elastic member is overcomewill the limiting portion 1352 of theblocking member 1350 and the limiting stage 1351 be separated. Thesurface of the limiting stage 1351 and the surface of the limitingportion 1352 are separated from each other further so that the externalport 1343 is opened. Then, the water outlet 1360 is opened, so that thewater in the water supply tank 1200 flows out from the water outlet1360.

In one embodiment, the water tank structure includes a unidirectionalair valve 1342, and the unidirectional air valve 1342 is configured onthe air inlet 1341. The unidirectional air valve 1342 allows air toenter the water storage cavity along the air inlet 1341. Theunidirectional air valve 1342 can ensure that the air outside the watersupply tank 1200 can enter the water storage cavity of the water supplytank 1200, and the water in the water storage cavity will not flow outof the water supply tank 1200 through the air inlet 1341. Theunidirectional air valve 1342 can be tubular, and the bottom of theunidirectional air valve 1342 can form a V-shape. The inner pipe wallson the opposite sides of the V-shaped pipe section are closed to eachother in a normal state and can be separated under the pressure formedwhen the pressure source 1300 is activated. Therefore, when the pressuresource 1300 is continuously pumping water, the negative pressure in thewater supply tank 1200 is continuously increased. When the air pressureoutside the water supply tank 1200 to the unidirectional air valve 1342is greater than the water pressure inside the water supply tank 1200 tothe unidirectional air valve 1342, the outside air of the water supplytank 1200 can enter the water supply tank 1200 through theunidirectional air valve 1342 along the air inlet 1341 to supplement theair (intake) of the water supply tank 1200. When the air pressure in thewater supply tank 1200 is balanced with the air pressure outside thewater supply tank 1200, the unidirectional air valve 1342 can be closedunder the pressure of the water pressure in the water supply tank 1200.That is, the inner pipe walls on the opposite sides of the V-shaped pipesection are closed to each other, so that the unidirectional gate valvecan be closed to prevent the water in the water supply tank 1200 fromflowing out of the water supply tank 1200 through the air inlet 1341.

In one embodiment, the water tank structure includes a first filterelement, and the first filter element is configured at the water outlet1360. Therefore, the water in the water supply tank 1200 can be filteredand then flow out through the water outlet 1360 to prevent the solidmatter in the water supply tank 1200 from clogging the water outlet 1360and downstream channel.

In one embodiment, the water tank structure includes an elastic snapstructure 1390, and the elastic snap structure 1390 is arranged on thewater supply tank 1200.
